If your air conditioner isn’t cooling your air anymore, you need reliable AC repairs to address the problem. The last thing you want to do is to run your AC constantly without getting any benefit from the expense. If you call an HVAC contractor, they have the tools and expertise to find the exact cause of the problem with the AC unit.
In the video here, an HVAC contractor troubleshoots problems with an AC unit that doesn’t cool the air anymore. First, he uses a diagnostic tool to figure out how the AC unit is behaving. In this case, the subcooling capacity of the unit had dropped significantly. To address this, he first adds more refrigerant to the system. This starts to fix the problem, which suggests that the problem could be a refrigerant leak. This is considered an AC system recharge.
To finish up the service call, he makes sure to inspect all of the elements of the AC system thoroughly. This ensures there are no additional problems contributing to the lack of cooling capacity.
If you’re having problems with your AC unit not cooling, an HVAC contractor can help you find the source of the problem.
